Speciication of Letters Patent.

To all whom, it may concern.-

Be it known that we, CUTHBERT B. LowRY, of Lexington, in the county ofFayette and State of Kentucky, and RICHARD BERNHARD, of Chicago, in thecounty of Cook and State of Illinois, have invented certain new anduseful Improvements in Wood-Impregnatin g Apparatus; and we do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappe'rtains to make and use the same.

The objects of this invention are to provide a wood-impregnatingapparatus so constructed as to obtain maximum capacity in the cylindercharges, to strengthen the construction of the car, to provide improvedmeans for limiting the amount of timber that can be placed on the carand to hold the same when submerged, and to simplify the construction ofthe track and guard rail fastenings.

The invention will be hereinafter fully set forth, and particularlypointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective withparts in section, showing the car within the preserving-cylinder. Fig. 2is a vertical sectional view on line 2 2, Fig. 3. Fig. 3 is afragmentary view of the car and vone of its wheels, a portion of theguard-rail being broken away. Fig. 4 is a section on line i 4, Fig. 2.Fig. 5 is a section on line 5 5, Fig. 3. Fig. 6 is a plan view ofa-portion of the car and trackrails. Fig. 7 is a side elevation with aportion of the car frame and bail. Fig. 8 is a view of the same parts atright angles to Fig. 7 Fig. 9 is a transverse sectional view through thecylinder, showing the carin place. Fig. 10 is a perspective view ofportions of the rails. Fig. 11 is a horizontal section of thecylinder'on line 1l 11, Fig. 9, with the car omitted. Fig. 12 is avertical section of the cylinder on line 12 12, Fig. 9. Fig. 13 is aplan'view of the chair for the guard and track rails, the rails beingbroken away. Fig. 14: is a sectional elevation of the combined track andguard rail chair for the innerv courses of the cylinder-shell. Fig. 15is a similar view of the same part for the outer courses of the shell.Figs. 16 and 17 are sectional elevations of the plain rail-chairs otlthe inner and outer courses, respectively.

Referring to the drawings, 1 designates the cylinder shell or casing,which, as shown in Figs. 11 and 12, is composed of inner and outercourses 2 and B-that is to say, the ends of the sectional members of theshelloverlap, each alternate section being on a plane within the nextadjacent sections. The track-rails 1 are preferably made of angle-barscut on the bottoms of their vertical legs to suit the shells of thecylinder. These track-rails are supported by chairs 5 6, which areattached to the shell at intervals by bolts or rivets 7, the number ofchairs depending on the load the rails are intended to support. Each ofthe chairs 5 has a horizontal iiange 8 and a vertical flange 9, thehorizontal portions of the rails 4: resting on the -horizontal flanges8, to some Vof which they are secu red by countersunk screws 10. (SeeFig. 10.) It is not necessary that the rails be fastened to all therail-chairs, (see Figs. 16 and 17,) since the flanges of the carwheelsaid in holding the rails on the chairs. Figs. 14 and 15 and 16 and 17illustrate the diderences in the chairs, those shown in Figs. 111 and 16being for the inner courses of the shell and those in Figs. 15and 17 forthe outer courses. Although we prefer that the vertical portions of therails be shaped to conform to the cylinder-shell, yet this is notnecessary. It depends entirely upon the load the rails have to carry,and suiiicient supporting strength can be obtained either by placing thechairs closer together or allowing the rails to bear on the shells.

12 designates a guard-rail in the form of an angle-bar, with itsvertical legs attached to the vertical lianges 9 of the rail-chairs bynutted bolts 13, such bolts being passed through slotted openings toallow for changes in temperature and irregularities in workmanship.These guard-rails, like the track-rails, are made in convenientsections.

It will be observed that the track-rails are located close to the bottomof the shell, so as to increase the available capacity of the cylinderfor receiving charges of material undergoing treatment. By this meansthe car will be much closer to the bottom of the shell than hasheretofore beenl possible. This car has a frame composed of fourprincipal memberstwo longitudinal side sills 111 and two transverse endsills 15-thelatter being formed to suitthe shape of theimpregnating-cylinder and of varying depth, depending upon the stressescaused by the weight of the timber on the car. In other words, the endsills are curved at their ends upwardly and outwardly, so that they notonly form the connections between the side sills, but also protect orretain the timber in position and serve as iixed guides in the pilingthereof on the car. These side and end sills are preferably made ofangle-bars, although we do not limit ourselves in this respect. They areconnected together by means of rivets passed through castings 16,located at their points of union, which castings are also provided withfianges 17, forming bearings for the wheel-axles 18, the latter beingheld to the side sills preferably by means of U-bolts 19. The wheels 2Oare bushed and fitted with roller-bearings, confined by means of washersor collars 21. (See Fig. 2.) To each of the end sills 15 is secured alaterallyextended lug 22, which travels in close proximity to theadjacent guard-rail 12, such lugs serving to prevent the car fromlifting off the rails when within the impregnating-cylinder.

23 23 designate two bails preferably formed from rigid Irods bent toconform to the upper portion of the cylinder-shell and removably securedto the ends of the end sills, so as to limit the loading of the timberand prevent the latter from contacting with the cylindershell. Each ofthese bails is formed with an angular end designed to extend through anopening in one of the flanges of its respective end sill, whereupon itis locked by pins 24, passed through openings in such angular ends, saidpins being preferably coiled at their other ends so as to loosely securethem tothe bail beyond the ends of the sills. To remove the bails, it isonly necessary to slide the looped end of pins 24 upwardly on the bails,whereupon the angular ends of the latter may be withdrawn from the holesin the end openings. Pins 25 prevent the looped ends of pins 24 fromsliding off the bails when the latter are removed.

The advantages of our invention are apparent to those skilled in theart. It will be readily seen by reference to Figs. 1 and 9 that bylocating the track-rails close to the bottom of the cylinder we areenabled to utilize the full available capacity of the cylinder forreceiving charges of material undergoing treatment, since the framing ofthe car is always close down to near the bottom of the cylinder. Alldanger of the car tilting' is overcome by the hooks thereof projectingbeneath the guard-rails. It will also be seen that we have providedextremely simple means for supporting the track-rails and guard-railsand securing them to the cylinder-shell and that by passing the boltsthrough slotted holes We can readily compensate for changes intemperature or irregularities in workmanship.
